Flexwatt is cheap compared to that pad you want....it gets much more warm and is great. I use 12" flexwatt on my rack, it's so amazing!!!!
Also, the acurite is awesome, I have 2, and if I had a viv, I would put it inside of the tank, but I use tubs so I performed the mod. They work great, 1 is up in the middle of the wall sticking out to tell me the room temp (cool side temp) and 2 in for warm side and humidity!!
